By far the most common and widely dist lihutcd species of the genus in the 

 Pliili])piues, and rather variable. Vidal's type is niin\itely matched bj- Elmer 

 O'l-'hi. and by the specimens from Rizal Province cited above. Quercus concentrica 

 Blanco non Lour., aiul <J. iiioliirca Blanco non Kumph.. are referred here, as 

 Blanco's descriptions apply closely to the present species. Quercus clemcntiana 

 Mas admitted by me on the strength of identifications made l)y ^'on Seemen, but 

 an examination of authentic material of King's species, shows that it is 

 distinct from Q. saleriinid. Tiie mature gians is about 2 cm long, and from l.S 

 to 2.4 cm in diameter. J.,ocal names, T., Jhr/joptuj, Ahii/tni, ex Blanco; ('(ledmi ex

This species is manifestly allied to Quercus soleriana Vidal, but is well char- 

 acterized by its very prominently caudate-acuminate leaves. It appears to be 

 rather local. King states that he can see no reason why this species should not 

 be reduced to Quercus lineala Blume, of the section Ci/clobahrnopsis, but its leaves 

 are entire, and recently collected material from the type locality shows it to 

 have erect male spikes, and therefore to be a true Cyclohalanus. \\'enzig 1. c. 

 states under Q. philippincnfiis: "Q. Uanosii DC. N. 235, Q. oralis P>lanco fl. dc 

 filip. (ed. 2) p. 502, DC. N. 236, Q. Bhincoi A. DC. N. 237 * * * sunt noiuiisi 

 formae Q. philippineusis DC." but Q. Uanosii is a species very distinct from 

 Q. philippinensis, while Q. hlaneoi is an exact synonym of Q. ovalis, which is 

 a species entirely difl'eroTit from both Q. Uanosii and <J. philippinensis, as shown 

 above.

Some of the specimens from the Province of lialaan were identified by Von 

 Seemen as Quercus hennellii Mu\., and others as Q. ucnzinianu King, but lliey
